Email Not Trumped

I’m using WordPress 1.02 on one of my blogs and noticed that when a commentro leaves their name and email without a web URI, the email address does not get hidden from the public.
Basically the email is not getting ‘trumped’ in a case where the URI is not filled out.
I also noticed that this is fixed in WP 1.2 where the above is not seen. However, I am not seeing myself upgrading this particular blog to 1.2 as of yet and was wondering if there is a fix for this in 1.02?
Thanks.
